If your Breville Bambino Plus is showing a ‘No Pressure’ error or producing weak espresso, it can be frustrating. Proper pressure is essential for optimal extraction, flavor, and crema. This guide provides practical, safe steps to diagnose and fix common causes of low or no pressure in your Breville espresso machine, helping you enjoy cafe-quality coffee at home.
Key Takeaways
| Check for blockages | Clogged filters or shower screens can cause pressure issues. |
| Inspect water filters | Impurities or clogged filters reduce water flow and pressure. |

| Verify machine setup | Incorrect portafilter placement or tamping can affect pressure. |
| Perform routine cleaning | Residual coffee oils or scale buildup hinder water flow. |

Step 4: Check the Grind Size and Tamping
- Use a fine, consistent grind suitable for espresso.
- Ensure you’re tamping evenly with firm pressure to avoid channeling.
Step 5: Run a Water Flush and Test
